(A) Ultrasonography, axial scan. Magnetic resonance, axial scans T1 weighted, (B) direct and (C) after paramagnetic contrast agent intravenous administration, hepatic arterial phase. (D) Spiral computed tomography, axial scan after iodinated contrast agent intravenous administration, portal venous phase. Triangular congested parenchymal area (white arrows); dilated biliary vessels (white arrowheads). (E) Surgical specimen. Opening longitudinally from the hilum to the glissonian surface. Triangular congested parenchymal area (white arrows); dilated biliary vessels (white arrowheads); main papillary tumour at the apex of congested parenchyma (black arrowhead); others papillary tumours within the congested area (black arrows). Note the correspondence between MR imaging and specimen. (F) Immunostaining for laminin-5 (cryostat sections) in metastatic tissue.
